Изменить значение переменной в Robot Framework

Введение

В Robot Framework нельзя просто объявить переменную с помощью = прямо в коде теста, как это делается в Python

Внутри одного ключа

Переменную, объявленную ранее в *** Variables *** можно изменить с помощью Set Variable

Область видимости - внутри ключевого слова (только в том же Keyword)

Set Global Variable

Чтобы изменённую переменную было видно в других ключах, можно использовать Set Global Variable
